Original application filed December 4,

To all whom it may concern:

Be it known that we, ARTH R M. WAITT, a resident of Sharon, county of Litchfield, and State-of Connecticut, andWnYMER H. WAITT, a resident of New York, county and State of New York, have inventedcertain new and useful Improvements in Car-Doors, of which the following is a full, clear, and exact description.

The present application is a division of an earlier application filed by us in the United States Patent Office, December 4, 1919.,Serial No. 7 34,911.

The invention relates to sliding doors for railway cars and seeks. to provide an improved construction for the side edges of the door which can be economically manufactured, is storm and spark proof and which cannot be tampered with by unauthorized persons without mutilating the door.

The invention consists in the features of improvement hereinafter set forth, illustrated in the difierent forms in the accompanying drawings and more particularly pointed out in the appended ClfilIIL;

In the drawings, Figure 1 is a side elevation of a portion of the freight car illustrating the door to which the present inven tion is applied. Fig. 2 is a horizontal section on the line 22 of'Fig. 1. Fig. 3 is a view similar to Fig. 2 illustrating a modified construction. Figs. 4 and 5 are horizontal sections illustrating further modifications. Fig. 6 is a detail section on the line 6-6 of Fig. 5.

The car body is provided with an opening which is closed by a sliding door 10. The door posts, at the sides of the door opening, are provided with portions which, as shown in Figs. 2 and 3, project outwardly beyond the outer face of the car formed by the siding or sheathing 12. The door is provided at its upper edge with a pair of supporting hangers 13 which are arranged to engage a suitable track member 14 secured to the side .of the car above the door opening. The lower edge of the door is held in place by brackets 15 which are fixed to the side of the car and cooperate with a flange 16 on the bottom portion of the door.

, Fig.2 illustrates the preferred construction for protecting the front and rear edges of the door. The United States Letters Patent No. 57 0,07 4 issued upon October 27, 1896,

to Arthur VVaitt, one of the present applicants, discloses a U-shaped guard sheath which is attached to the'inner face of the door at its rear edge. This construction requires the use ofja special metal shape and the screws or nails used to fasten it in posi-' loose they sometimes obstruct the opening tion are so located that when they become in "the U-shaped sheath plate and thuspreyond the filler piece and is arranged to cooperate with a fixed guard plate or strip 20 which is fixed to the outer face of theprojecting portion of the door post 11 by screws 21. The rear edge of the guard strip 20 projects rearwardly beyond the projecting portion-of the door post and the forward edge of the guard strip. 17 is adapted to overlap the same, as shownin Fig. 2, to-

effectively prevent the entrance of. moisture and cinders at the rear edge of the door. The construction is al so.'so arranged that the fastening means for the guard strip 17 are not accessible when the door is closed so that the door cannot be pried open for pilfering at its rear edge. It should be noted that the guard strip 17 is secured to the door from the inside and at its rear edge, and that the fastening means is arranged rearwardly' of the forwardly projectingedge of the strip which co iperates with the rearwardly projecting edge portion of the guard strip 20. In this construction, the fastening screws, even if they work loose, cannot obstruct the entrance of the rear edge of the guard strip 20 into the space 22 between the inner face of the door and the forward edge portion of the guard strip 17. The protective means for the rear edge of the door shown in Fig. 3 is similar to that shown in Fig. 2, except that the guard fixed to the car body comprises an angle bar or strip 23, which is L-shaped in section and is secured to the rear face of the projecting portion of the door post by screws 241-.

The forward edge of the door overlaps the outer face of the forward door post 11 and abuts against a projecting door stop 25 which, in the usual manner, is fixed to the door post. The abutting edge of the door or of the door post, or the abutting edges of both of these parts are rabbeted or so shaped that an irregular or broken joint is formed at the forward edge of the door opening when the door is closed. The abutting edges of the door and door stop are also shaped as to form an open vertical channel or passage 26 of considerable cross-section which, in connection with the broken joint ed contact prevent'the entrance of water or sparks into the door opening. ,Anyvmoisture or cinders passing between the'front edge ofjthe door and the door stop will be readily deflected downwardly through the channel and will pass out of its lower open end and will not, therefore, continue through the circuitous passage between the door, door stop and post, into the door opening. In the construction shown in Fig. 2, the outer thickness of the door extends be yond the inner thickness and the inner portion of the door stop is provided with a laterally projecting portion 27 against which the inner thickness of the door abuts. The part 27 is spaced from the outer thickness of the door to form the channel 26. A bracket 28 is fixed to the side of the door and overlaps the outer face of the door stop. Its rearwardly projecting, curved end is arranged to engage the forward edge of the door, when the latter is closed, and hold it in snug engagement with the face of the door post. In the construction shown in Fig. 3, the laterally projecting part on the door stop is omitted.

Fig. land Figs. 5 and 6 illustrate modifications of the means for protecting the rear edge of the door. In the construction shown in Fig. 4, the forward edge of the protecting guard strip 17 is inturned.

In this form, the siding 12 is suitably recessed or cut away opposite the inturned inner end of the guard strip to form a vertical channel 29. Any cinders, moisture or the like entering the space between the rear edge of the door and the side of the car will be deflected by the inturned end of the guard strip 17 into the vertical channel 29 and will escape through its lower open end and. will not find its way around the edges of the guard strips 17 and 20 into the door opening.

In the form shown in Figs. 5 and 6, the guard strip 17" is held in an inwardly inclined position by a wedge-shaped filler piece 19: and the cooperating part on the car comprises-a series of Lshaped brackets 30 fixed to the rear face of the projecting portion of the door post by screws 31. The brackets 30 cooperate with the guard flange to effectively hold the rear edge of the door in position and the inclined position of the guard flange 17 affords an open channel 32 of considerable area between its inwardly projecting portion and the inner face of the door, and any moisture, cinders or the like which pass around the edge of the guard strip will pass downwardly through the lower open end of this-channel.

It is obvious that numerous changes may be made in the detailsset forth without departure from the-essentials of the invention as defined in the claim.

Ne claim as our invention In combination, a car body having a door opening, door posts at the sides of said opening, a sliding door arranged to overlap said door posts in its closed position, a door stop fixed to the forward door post against which the forward edge of said doo" abuts, when in closed position, the inner portion of the front edge of said door being reduced in thickness to form a vertical channel open at its bottom, substantially as described.
